I have shown my invention in the present instance embodied in aRemington electrified bookkeeping machine such as is disclosed inmyapplication Ser. No. 510,941, filed Jan. 24, 1931, but have only shownso much of said machine as is necessary to arrive at an understanding ofthe present invention in its embodiment therein.

While the features of the present invention were designed primarily forembodiment in the above-mentioned machine and may be included thereinwithout modifying, or materially modifying, the existing structuralfeatures thereof, it should be understood that the invention is notrestricted to'the use in such machine but may be employed intypewritingand like machines generally wherever found available.

The Remington electrified bookkeeping machine has a non-shifting platenand writes only upper case characters. The means employed in saidmachine for facilitating the introduction of work sheets into themachine from in front of and beneath the platen and for handling thecollating work sheets are like those disclosed in the application ofFrederick A. Hart and Sigurd L. Walsoe, Ser. No. 221,543, filed Sept.23, 1927.

The present inventionus in the nature of improvements on theconstruction disclosed in said last mentioned application and providesfor writing lower case characters 'as wen as upper case characters, thework sheet controlling means and the parts associated therewithfunctioning in either case position to which the platen may be shifted.

Before describing the construction, brief reference will be made to oneof the various uses to which the invention may be put.

The machine being first conditioned for receiving work sheets, a recordsheet R with an outer or underlying carbon sheet C are introduced intothe machine from the rear of the platen between the platen/and the uppercurved deflector plate beneath the platen. The leading ends of thesesheets are brought forward and upward and arranged beneath the upperfeed rollers at the top of the platen. A statement sheet S, ledger sheetL and interposed carbon sheet 0 are then introduced rearward into'themachine from in front of and beneath the platen, with the statementsheet outermost. These last mentioned sheets are inserted bottom endsfirst into a separate channel between the upper and lower curved paperdeflectors beneath the platen. When these sheets S and L have beenproperly collated with reference to each other and the previouslyintroduced and positioned record sheet R. and the printing line, thefeed rollers are applied and the machine operated to effect asimultaneous entry of the items on the statement sheet S, ledger sheet Land record sheet R. When the entries are finished, the statement sheetand the ledger sheet are removed and new ones inserted; the record sheetand its companion carbon sheet C remaining in the machine and taking anaccumulation of the items written on the various statement and ledgersheets.

The foregoing is but one of the various uses to which the presentmachine may be put and itis one of the general objects of the presentinvention to provide means for rapidly, successively and accuratelyintroducing and collating work sheets in the machine, as hereinbeforeindicated.

The Remington electrified bookkeeping machine, and that disclosedherein, has a main frame comprising two sections 1 and 2 hinged togetherat 3 in the rear thereof to enable the upper section 1 to be swung backon the lower section to give access to the parts contained withn theframe and to move down to the position of useshown in Fig. 8. Poweractuated mechanism (not shown) is contained within the base section 2 ofthe frame and 'coacts with various parts con trolled. thereby, such forexample as the numeral printing type bars 4 and alphabet printing typebars 5 as well as other parts of the mach'ne.

The construction is such that the coacting parts ed for vertical caseshifting movement on parallel links 12. The case shifting movement ofthe platen frame to and from upper case position is limited byadjustable stops 13 and 14 which coact with coiled spring 15 (see Fig.3) surrounding the bearing of the platen shaft.

For the purpose-of the present invention it is sufficient to illustratea manually actuated case shift mechanism, although it will be understoodthat power actuated case shift-mechanism may be employed. In the presentinstance the case shift mechanism includes a grooved bearing roller 16(see Fig. 8) carried by a cross bar 17 that constitutes a part of theplaten frame. This roller is supported on a shift rail 18 carried byupright supporting links 19 pivoted at their lower ends, at 20, to leverarms 21 arranged at oppo site sides of the machine and connected to movetogether by suitable means (not shown). Each lever arm 21 is pivoted tothe upper section 1 of the frame, at 22, and extends forward of itspivot and is provided with a case shift key 23. A counter-balance spring24 is connected at one end to each of the links 19 and is anchored atits op- The numeral and alphabet printing type bars 4 and 5 are adaptedto impact against the front face of the platen, or the paper carriedthereby, as indicated in Fig. 12 in which the dot and dash line arepresents the printing line. These type 159 bars may be actuated in anysuitable manner such, for example, as indicated. in my hereinbeforementioned application in which numeral printing key levers 25 arefulcrumed on' a ful-- crum bar 26 secured to the frame section 1 andeach provided with a finger key 27. Each numeral key is provided with adepending trip 28 by which power controlled actuating means (not shown)for the numeral printing type bars 5 and the computing mechanism of themachine are actuated. Each numeral printing type bar 4 is.

operatively connected to a sub-lever 29 pivoted at 30 and connected at31 to a sub-lever 32 that is fulcrumed on the fulcrumbar 26 and coactswith a power actuated member 33 to effect an operation of thecorresponding type bar on the depression of a numeral printing-key 27.

The mechanism of my present invention for controlling and collating thework sheets will now be described.

The platen frame 10 which supports the platen edge thereof on a rod 39;the deflector plate terminatfng at its forward edge below the printingline. Thisdeflector provides, a channel 40 between the platen and saiddeflector plate to receive a forwardly introduced record sheet R and acompanion carbon sheet C which are carried for- .ward and upward beneaththe usual set of feed rol1ers 41 carried by spring pressed arms 42 inthe usual manner. The cross bar or supporting spindle 43 for the feedrollers 41, together with the arms 42, are in the nature of a pivotedspring pressed bail that may be swung upward to ineffective position ordown to the effective position, shown in Fig. 1.

Beneath the curved deflector plate 38 is a second curved deflector plate44 maintained spaced apart from thedeflector plate 38 by end spacingbars 45 providing a rigid connection-between the two deflectors whichconstitute a chute. A second channel 46- is thus provided between thetwo deflectors for the backward insertion from in front of and beneaththe platen of a statement sheet S and ledger sheet Land an interposedcarbon'sheet c. Pivoted at 47 along the front end of the fixed deflectorplate 46 is a deflector section 48 which forms a continuation of thedeflector 46 and terminates at its front end below the printing line.This pivoted section 48 has a pivotal movement from the positionindicated in Fig. 1 to that indicated in Fig. 2. This is to provide anenlarged open mouth at thereceiving end of the channel 46 to receive anddirect the work sheets S and L with the interposed carbon sheet 0 intosaid channel. When themachine is in condition for writing, as shown inFig. 1, the pivoted section 48 is closed against thework sheets in thechannel 46 and holds them more or less snug against the face of theplaten. The opening'and closing of this pivoted deflector section 48 isautomatically controlled, as will hereinafter more clearly appear. l

The feed rollers which coact with the platen and by which the worksheets are'controlled and fedwith the aid of the platenare preferablyarranged in two sets. Outside terminal or marginal feed rollers 49 areemployed ordinarily to coactwith the marginal portions of acomparatively wide ledger sheet-L andits overlying carbon shee 0,whereas the intermediate feed rollers 50 'ar intended to coact with themarginal portions of: anarrower statement sheet S. Both sets of thesefeedrollers cooperate with the platen above the printing line andarearranged in substantial alignment as indicated in Fig. 4. These feedrollers are mounted and controlled for movement from the effectiveposition shown in Fig. 1, down to the inefiective position shown in Fig.2 where they not onlyoifer no obstruction to the introduction of a worksheet into the channel 46, but are positioned where they constitute asupport and guide for the work sheets as they are intro-. duced intosaid channel. The means for thus supporting and guiding the feed rollersand for applying them with .an effective pressure to the work sheet willnow be described.

Referring more particularly to Fig. 12 it will be seen that each feedroller, whether it be a feed roller 49 or 50, is supported on a pivotrod 51 which unites two slides or feed roller carriers 52 arranged onopposite sides of the feed roller. These slides are fixedly united notonly by the pivot rod 51 but by a cross rod 53. Each slide atits forwardend is provided with a longitudinally extending slot 54 in whichisreceived a rock shaft 55 to provide a support for and afford a slidingand pivotal movement of each of the slides 52 thereon. Each slide isalso provided with an aligned cam slot 56 which extends longitudinallyof its slide and has at its forward end an upwardly directed extensionslot 57. A guide pin 58 is received in each cam slot 56-5'7 and coactstherewith to guide and determine the direction of movement of the slidesfrom the full line to the dotted line position in Fig'I 12 and viceversa; the slots 56-57 operating in the nature of cam slots which coactwth the relatively fixed pins 58. When, therefore, pressure is exertedon the slides by their toggles to apply the feed roller as willhereinafter appear, the slides will first be moved upward from theineffective dotted line position, shown in Fig. 12 to the effectiveposition, indicated in full lines in this. figure. In withdrawing a feedroller this movement of the slides will be reversed.

The supports for each feed roller comprise two sheet metal bracketplates 59 shown in detail inFig. 13. ,Each of these plates carries oneof the guide pins 58 by which the companion slide 52 is supportedintermediate its ends, and is apertured at '60 to provide a pivotalbearing for the 130 bracket plate or support on the rock shaft 5-5.

An inwardly extending lug 61 on each support 59. constitutes a bearingface against which a plate 62 is seated when the parts are assembled,

as shown in Fig. 1.- A central aperture 63 in the plate 62 receives aheaded screw 64. The forward threaded end of this screw is received in atapped opening in a cross bar 65 connected to a u-shaped supportingbracket 66. Each bracket 66 has a; tongueeand-groove engagement, asindicated at 6'7, with a bar 68 secured by screws 69 tothe front crossbar 34 of the platen frame and extending throughout, or substantiallythroughout, the length thereof. The purpose of this mounting of eachbracket 66 on the supportingbar 68 is to afford an adjustment of each ofsaid brackets together with the parts carried thereby e to any desiredposition longitudinally of the platen so that each feed. roller, itssupporting, 1 50 guiding and controlling means, may be adjusted as asingle unit longitudinally of the platen.

A coiled expansion spring 70 is provided between the head of each screw64 and the companion plate 62. The force of this spring tends therefore,to maintain the associated carriers or brackets 59 against pivotaldisplacement from the position they normally assume in the machine. Insuch position a stop pin 71 on each plate 59 bears against the companionupright arm of the associated U-shaped bracket 66 and limits the pivotalmovement of the carrier or plate in one direction under the pressure ofits spring '70. When, however, the associated slides 52 are moved to thefull line position shown in Fig. 12, the companion feed roller will becaused to bear with a positive pressure against the platen and by ridingup on the curved face thereof will flex the spring '70, and the reactionof said spring will be exerted against the'feed roller to maintain itunder spring pressure against the platen or the work sheet thereon. Y

There is a distinct advantage in making the support for each of the feedrollers in two separate members 59 as shown, in that the parts arecheaper to manufacture, and they can be more readily assembled with thecompanion parts of each unit. Moreover, by making the supports in twoparts as indicated, they may be used in employing rollers of differentlengths by merely increasing or decreasing the length of the associatedmember 62 and the spacing sleeves to be hereinafter described.

The means for moving the feed rollers 49 and 50 to and from effectiveposition as hereinbefore described will now be set forth.

Each feed roller is moved to and from elfective position by toggles, thestraightening of the toggles positively applying the feed rollers, asindicated in Figs. 1 and 5, and the breaking of the toggles moving theassociated feed roller to ineffective position, as shown in Fig. 2. Eachtoggle comprises a toggle link '72 pivotally connected at one end to thecross rod 53 which unites the companion slides 52, and pivoted at itsother end, at 73, to a toggle lever 74. Each toggle lever '74 is mountedon the rock shaft 55 and .extends upward and forward therefrom where itis connected to a finger piece 75 that is interposed between the twocompanion toggle levers 74. Companion toggle links 72 are maintainedspaced apart on the cross rod 53 by spacing sleeves 76 and theassociated toggle levers 74 are maintained spaced apart and in properposition between the upright arms of the bracket support 66 by spacingsleeves 77 and. the companion finger piece 75. a finger piece 75 isshifted forward, the companion toggle members 74, 72 will bestraightened to the Fig; 1 position, thereby first elevating thecompanion slides 52 from the Fig. 2 position. In this movement theslides receive a pivotal motion around the rock shaft 55 until thelowermost horizontal part of the cam slot 56 is reached when the slidesreceive a further rectilinear movement to bring the feed rollers incontact with the platen and the work sheet thereon, as indicated inFig. 1. The straightening of the toggle exerts a positive force againstthe feed roller to cause it to ride up on the curved surface of theplaten and thereby stress the companion spring 70. so that the reactionof said spring will be exerted against the feed roller.

When the finger piece is moved in the opposite directiomthe toggle willbe broken, thus reversing the movement of the slides 5'7 and causingthem first to receive a forward rectilinear movement and then a downwardmovement from the position shown in the dotted line position in Fig. 12and to that indicated in Fig. 2; this latter or downward movement beingdue of course to the fact that the pins 58 at this time engage theupright portions 57 of the cam slots and cause the slides to receive apivotal downward movement at this time.

Depending somewhat on the character of the work to be performed, thetoggle levers '74 may be connected to the rock shaft 55 to be turnedthereby, or the toggle lever 74 may be loosely mounted on the shaft toreceive a movement independently thereof under control of the fingerpieces 75. The toggle levers '24 of the outermost feed rollers 49 areusually connected to the rock shaft to turn therewith, each of suchtoggle levers being'provided with an integral spline projection 78(see-Fig. 14) that takes within a V-shaped spline groove 79 in the rockshaft 55. In a like manner the toggle lever 74 for the inner set of feedrollers 50 may be connected to turn with the rock shaft 55, butpreferably these are devoid of the spline projections '78 and are freeto turn independently on the rock shaft 55, so as to enable the feedrollers 50 to be separately applied to the work sheets with the aid ofthe finger pieces 75.

, The rock shaft 55 preferably extends throughl out the length of thecarriage and is supported near its ends in bearing openings in the sideplates of the platen frame 10 as well-as receiving support intermediateits ends in the brackets 66. The left-hand end of this shaft is extendedbeyond the companion side plate of a platen frame and has a toothsegment or sector 80 secured thereto, as shown in Figs. 3 and 5. Thistooth segment 80 engages a companion sector 81 and is provided with ahub 80 which is preferably adjustably secured to the rock shaft 55 bytwo screws 80 80". These screws are received in tapped openings in thehub 80 and their pointed ends extend into a. V-shaped groove 79 in theshaft 55, one screw bearing against one side of the groove and the otheragainst the other side of the groove, as shown in Fig. 15. By backing upone screw and advancing the other a rotative adjust--. ment of thesector 80 on the shaft 55 in either direction may be readily effected.The sector 81 is mounted on a short shaft 82 that receives a bearing inthe companion side plate of the platen frame 10. The inner end of thisshaft 82 is fixedly connected to a crank arm or manually controlledactuating member 83 that extends upward and is provided with a fingerpiece at the upper end thereof. A rearward movement of the arm 83 fromthe Fig. 2 position to the Fig. 1 position, is

effective. to transmit ananti-clockwise movement to therock shaft 55which in turn is effective to straighten all of the toggles that areconnected to therock shaft and to move the feed rollers thus connectedfrom the Fig.2 to the Fig. 1 position and apply such feed rollers to theplaten or the work sheets thereon. A movement of the arm 83 in theopposite direction is effective to withdraw the feed rollers connectedtherewith from the platen or from the Fig. 1 to the Fig. 2 position. Theoutside terminal feed rollers 49 having been applied by movement of therock shaft 55 in the manner described, are effective to engage and holdthe previously adjusted wider ledger sheet L in position. Thesubsequently introduced,

relatively narrower, statement sheet S and carbon sheet c may then beplaced in position and collated with reference to the ledger sheet andthe separately applied feed rollers 50 may then be moved to effectiveposition-to engage the statement sheet.

erted to move the line indicator 84 to effective,

indicating, position, as shown in Fig. 1. One of the arms 85 is extendedupward to form an arm or actuating member 85 provided with a fingerpiece 88 at the terminal portion thereof. The upwardly extending arm 85coacts with a stop 89 as shown in Fig. 1 to limit the movement of thearms 85 and the line indicator 84 carried thereby in one direction ortowards the platen. The stop 89 is eccentrically mounted as indicated at90 in Fig. 1 so as to provide for adjusting the stop.

While the arm 85 may be actuated at will to control the line indicatormeans alsoare pro-- vided for automatically actuating the line indicatorunder control of the arm 83.. It is desirable to move the line indicator84 to its indicating position at the first part of the movement of thefeed rollers toward the platen, and to move the line indicator away fromeffective, or indicating, position at the first part of the movement ofthe feed rollers away from the platen. The means for accomplishing theseresults will now be described.

Referring more particularly to Fig. 5, it will be seen that a headedscrew, 91 projects laterally from the arm 83 and constitutes a pivotal.connection for a link92. The opposite end of this link carries a pin 93which projects through the horizontal slot 94 in atnxed guide plate 95secured by screws 96 to the" adjacent side plate of the platen frame 10.The outer end of this pin 93 is headed, as indicated at 97 in Fig. 3,

to retain the pin 93 in its guide slot 94. A second link 98 is pivotallyconnected to the pivot screw 91 and is loosely seated thereon to afforda lateral movement of the link 98 towards and from the link 92. Thelower end of the link 98 is mounted in a like manner on the pin 93. A

leaf spring 99 is securedintermediate its. ends at 100 to the link 92and bears at its free ends against the link 98 to normally maintain saidlink 98 against the head of the screw 91 and the inner head of the pin93. The link 98 intermediate its ends is provided with a laterallyextending projection or abutment 101, opposite sides 102 and 103 ofwhich are inclined to form cam faces for purposes which will hereinaftermore clearly appear. In the movement of the arm 83 to the rear from theFig. 2 position, the projection or abutment 101 will engage the uprightarm 85*, as indicated in Fig. 2, at the first part of the motion of thearm 83, and-will move the arm 85 with the arm 83, thereby moving theline indicator from the ineffective, Fig. 2, position to the effective,Fig. 1, position. The movement of the arm 85 with the lever arm 83 willcontinue until the arm 85 reaches its stop 89 and is arrested thereby,as shown in Fig. 14. From a consideration of this figure it will be seenthat at this time the feed rollers have not quite reached the platen 11but are brought sufficiently close thereto to bear against the worksheets with sufllcient pressure to maintain them against accidentaldisplacement but with suflicient freedom to enable the work sheets to beadjusted relatively to the line indicator 84 which at this time hascompleted its movement to indicating position. When the arm 85 coactswith the stop 89 as pointed out above, sufficient resistance to thefurther movement of the arm 83 will be felt bythe operator to indicateto her that further rearward movement of the arm 83 should notbe exerteduntil the work sheets L and S have been properly adjusted, and while theparts are maintained in the Fig. 14 position..

However, after the adjustment of the work sheets L and Shasbeeneffected, the operator 'will exert a further rearward pressure onthe arm 85, thereby forcing the link 98 laterally with a warming actionagainst the force of the spring 99 which bears against said link. The

effect of thus camming' the. link 98 to one side is to enable theabutment orcam 101 to ride over and past the arm 85 while the latter'isheld against its stop 89, and thus enable the earn 101 to pass to theopposite side of the lever arm 85 in a position to engage it immediatelyon the return movement of the arm 83 and its link 98. This relativeposition of the parts is shown in Fig. 3. Therefore, as soon as the arm83 is moved forward to release the feed rollers, the arm 85 will becarried forward with the link 98, thereby withdrawing the line indicatorfrom effective position during the first part of the movement of thefeed rollers away from theplaten. In this return movement of the arm 83to its forward position, the arm 85 will be brought in contact with astop pin 104 carried by the fixed guide 95 and arrest it, whilev the arm83 continues its forward motion independently of the arm 85. The effectofthis continued forward motion of the arm 83 is to deflect the springpressed link 98 outwardly towards the link 92 by the camming action of.the abutment 101 against the arm 85 as the cam rides over the arm to aposition in front pf it, as indicated in Fig. 2. Due to thisdisplacement of the abutment 101 in front of instead of behind the arm85, the parts will be conditioned to move the line indicator toeffective position as soon as the arm 83 is next moved rearward to bringabout a movement of the feed rollers to efiective position.

- From an inspection of Fig. 13 it-will be seen that each of theplatesor brackets 59 is provided with an inwardly extending projection 105that constitutes a stop for the associated toggle arm 74 to limit themotion thereof and the movement of the toggles to straightened position,as indicated in Fig. 5 This brings the toggle members slightly over thedead center and locks themin such position. I

I have provided means in the present construction for automaticallylowering the usual ribbon vibrator 106 from normal position when thedeflector section 48 is lowered to the open-position shown in Fig. 2 andthe machine is thus conditioned to receive the work sheets. The ribbonvibratoris carried by an arm 107, as

shown 2, which in turnis mounted on a ribbon vibrator support, indicatedas a whole by the reference numeral 108. This ribbon v1- bon vibratorsupport 108 and carries an antifriction roller 112 at the upper endthereof. This roller is adapted to bear against the lower edge of asheet metal flange 113 which extends throughout the length of the platenand is fixedly secured to the rock shaft 86 on which the arms 85 aremounted. Upwardly extending fingers 114 are also connected to the rockshaft 86 and are adapted to coact with the pivoted deflector section48,-as shown in Figs. 1 and 4, to

turn said deflector section around its pivot 47 from the Fig. 2 to theFig. 1 position when the feed rollers are applied to the platen. Whenthe arm 83 is moved forward to the Fi 3 position, the pivoted deflectorsection 48 is automatically moved down to the Fig. 2' position by theturning movement of the fingers 114 with the rock shaft 86 to which theyare secured. This same movement of the rock shaft is effective to lowerthe ribbon vibrator carrier 108, and to lower the vibrator from itsnormal position and thereby give greater clearance for the introductionof work sheets into the channel 46.

I also have provided means for automatically locking the numeral keys ofthe machine against actuation at this time. Referring more particularlyto Fig. 8 it will be seen that the ribbon vibrator carrier 108 hasconnected to one. of its parallel links 109 a rearwardly extending arm115 which is fixedly secured thereto. The rear end of this arm carries apin 116 that is received in the forked end 117 of an arm 118 pivoted toturn on fixed pivot 119. The arm 118 extends rearward beyond its pivotto provide a second arm 120 to which is'attached an adjustable device121 to which is pivoted, at 122, a depending controlling member 123.This controlling member is provided with two cams 124 and 125 and isguided in its up and down movement by the following means.

Referring more specifically to Figs. 9,1!) and 11, it willbe seen thatthe controlling member 123 is received between and embraced on oppositesides by a roller 126 and a disk-like guide member 127 coextensive withthe dimensions of the bearing roller 126. The roller and disk-like guidemember are supported and maintained spaced apart on a pivot pin 128riveted at 129 to a bracket am 130 secured by screws to a second bracket131, which in turn is secured by screws 132 tofthe upper frame section 1of the machine in the rear thereof. The front cam-carrying face of thecontrolling member 123 coacts with an anti-frictionroller 133 which iscarried by and extends laterally from one section 134 of a horizontallydisposed two-part actuating member or link, the other section of whichis represented at 135. Pins 136, 137 project laterally from the members135 and 134 respectively and are connected by a contractile spring 138.These two sections 134 and 135 of the link have a pin and slotconnection indicated at 139, 140, by which the sections may be movedlengthwise relatively one to the other, as will hereinafter more clearlyappear. The link section 134 receives a support on the hereinbeforementioned roller 126 and is guided in its movement thereon by extendingit through a guide slot 141 in a bracket arm'142 which forms part of thebracket 130, hereinbefore referred to. The bearing roller 126 thereforeconstitutes a support at the rear end foi the two-part link comprising.the sections 134 and 135, whereas the forwardend of this link ispivoted at'143 to a depending'lever arm 144 mounted to turn on a fixedpivot 145. The lower end of this lever arm is pivoted to anotherforwardly extending link 146 which has its forward end pivoted to an arm147 of a key locking mechanism, which may be of any suitableconstruction but which as shown in the present instance is of thecharacter disclosed in my application Ser. No. 549,852, filed July 10,1931. The arm 147'projects from a rock shaft 148 and said shaft also hasfixed thereon a locking blade 149 that is adapted to be projectedthrough a slot in a housing 150 that receives a series of locking balls151 in a channel therein. The housing is also slotted to receive the keylevers 152 of the numeral keys 2?, so that said levers may be controlledby the locking balls to afford an actuation of only one lever at a time;there being sufficient room between adjacent balls for the reception ofonly one key lever at a time. If, therefore, one of the'key levers 152is depressed, all of the other of such levers are prevented from beingdepressed by the closed locking balls of the series. The looking blade149 when shifted between two adjacent balls has the same effect as thedepression of one of the numeral keys so that when said locking blade isforced between adjacent balls all of the numeral keys will be lockedagainst depression.

' It will be understood, therefore, that when the parts are conditionedas shown in Fig. 2 for the introduction and collation of the worksheets, this results in lowering the ribbon vibrator support 108 105 andtransmitting motion therefrom through the arms 115, 118, 120 and thecontrolling member 123 to effect a longitudinal movement of the latter,with the result that one of the cams or 124 thereon will coact withthe'two-part link 134, 135, causing it to be moved forward and throughthe lever 144 and link 146 to rock the shaft 148 in an anti-clockwisedirection. The effect of this is to insert the locking blade 149 betweenadja-' cent balls and lock the numeral keys against depression. Theparts will be retained in this condition as long as the devices of thepaper controlling mechanism, etc., are retained in the position shown inFig. 2. It follows, therefore, that. at this time the printing keys 27are locked 120 against depression thereby preventing an operation of theparts controlled thereby including the printing instrumentalities andthe computing mechanism and results in preventing injury to the machineas well as a false operation. Thus, 5 should the operator at this timebe able to actuate the numeral printing type bars, they would be apt tocollide with the feed rollers as will be understood from a considerationof Fig. 12; said feed rollers at this time being in a line of travelthat intercepts the type bars. Therefore, aside from the possible injuryto the parts, a non printing and false operation would follow.

It will be understood that the construction is such that in the caseshifting movement of the platen the ribbon vibrator support 108 isautomatically elevated by its springs 110 with the platen as the latteris shifted to upper case position. The effect, therefore, of thismovement of the ribbon vibrator support is to shift the train 143 ofconnections intermediate said support and the controlling member 123.From a consideration of Figs. 16, 17, 18 and 19, it will be understoodthat when the platen is in the lower or normal case position asrepresented in Fig. 16, and the feed rollers 49 are applied to theplaten, an actuation of the arm 83 will result in lowering the ribbonvibrator support 108 to the Fig. 17 position, thereby actuating thecontrolling member l23 through I the intermediate train of connectionswith the result that the cam 124 will shift the two-part link Fig. 17position.

On the other hand, if the platen should be shifted tothe upper caseposition, the result is that the ribbon vibrator support 108 will followup the shifted platen to the Fig. 18 position in order to enable/thevibrator to be maintained in the same relation to the printing line thatit does when the platen is in the lower case position. This results inshifting the train of connections between the ribbonvibrator support 108and the controlling member 4'23 to the Fig. 18 position. In turn thisresults in moving the cam 124 upward out of cooperative relation withthe antifriction roller 133 and bringing the cam 125 on the controllingmember into cooperative relation with said anti-friction roller, asshown in Fig. 18.- It follows therefore that if the arm 83 should bemoved forward from the Fig. 18 position to release the feed rollers 49,or all of those which may be connected to the rock shaft 55, then thecontrolling member 123, through the intermediate train of connections,will be moved to the Fig;

19 position. This results in causing the cam 125 to coact vwth theanti-friction roller 133 and move the two-part link 134, 135 forward,thus locking the numeral keys against depression. This condition of theparts is illustrated in Fig. 19.

It follows from what has been pointed out above that notwithstanding thefact that the case shifting movement of the platen changes the relationof the train of connections to the key locking mechanism, the latterwill, nevertheless, operate effectively in either case position of theplaten when the machine is not conditioned to, receive the writing, andthe lock is automatically released in either case position of the platenwhen the machine is properly conditioned to receive the writing.

The Remington electrified machine is provided with an automatic poweractuated carriage return mechanism for returning the carriage to thebeginning of the line position when an end of the line is reached andfor simultaneously line spacing the work sheets. This condition providesa favorable position of. the carriage for" withdrawing the writtenstatement and ledger sheets from the machine and for introducing a newstatement and ledger sheet into the machine. In the present constructionI have provided a directing shield on the top plate '7 that coacts withthe parts when the carriage is disposed at the righthand end of itstravel, to facilitate the introduction of the new statement and ledgersheets into the machine. This deflector plate and the means for mountingit will now be described.

Referring more particularly to Figs. 4, 6 and 7, it will be seen that adeflector plate, designated as a whole by the reference numeral 153, hasa rearwardly and downwardly inclined face 154 that constitutes in effecta continuation of the 'at its left-hand end portion, as indicated at 156in Fig. 4. This deflector 153 may be mounted in any suitable manner, butI prefer to pivot it at 157 on brackets 158. A stop arm 159 on eachbracket supports the deflector in its normal position against thepressure of coiledsprings 160-, each of which at one end engages thedeflector and -at its opposite end is anchored on the associatedbracket. The pressure of the springs 160 is very light and enables thedeflector to be lifted away from its normal position in the event thatthe closely positioned deflector 48 should collide therewith. I preferto mount the supporting brackets 158 on the right-hand side of the topplate 7 of the machine for adjustment fore and aftof the machine. Thisis effected in the present instance by slotting the base of each bracketat 161 and providing headed clamping screws 162, the stems of whichenter the slots 161 and engage at their threaded ends in tapped openingsin the top plate.

I have hereinbefore pointed out that the memconnection is to afford arelative movement between the two sections of and a shortening of thelink in the event that it should receive a forward thrust under theaction of the control member 123 at a time when the ball lock is held inthe locked position by a depressed numeral key 27. At this time thelocking blade or arm 149 cannot enter between adjacent balls in the balllock. Due, however, to the provision of the spring 138 no injury canresult at this time by an actuation of the arm 83 to condition themachine to receive the worksheets. The effect of this operationwouldmerely result in moving the link section 134 forward against theforce of its spring- 138 while the forward section of the link is'heldagainst forward movement. However, as soon as the operator releases thedepressed key 27 and allows it to. return to normal position, the forceof the spring 138 will move the link section 135 forward, therebylocking the keys against operation until such time as the arm 83 isshifted to condition the machine for writing.

The two-part, link 134, 135has another function which will now bedescribed. An upwardly extending arm 163 projects from a rock shaft 164.The upper end of this arm 163 carries a laterally projecting pin orheaded screw 165 that extends through a slot 166 in the link section135, as best shown in Fig. 10. Therock shaft 164 also carries adepending arm 16'] which is controlled from the tabulator mechanism (notshown) in order to effect a forward movement of the two-part link 134,135 to actuate the ball lock and thereby prevent a depression of any ofthe numeral keys at the time that tabulator mechanism is operated, asdisclosed in my co-pending application between the types on each typebar in order to register substantially with the upper ends of theprinted lower .case characters. When the line indicator moves toineffective position, it moves forward and downward to the dotted lineposition showri in .Fig. 12. Whom-however, theplaten is shifted to uppercase position, the line indicator will shift upward with it, and inindicating position will be disposed as shown at 84 in Fig. 12

where it will register substantially with the. upper ends of upper casecharacters printed from the saw outermost types on the type bars. Atthis time the outermost types will pass just beneath the line indicatingwire. Therefore, in either case position of the platen the lineindicator 84 will substantially indicate where the upper ends of thewritten characters are to appear, whether such characters be upper orlower case characters.

From the foregoing description it will beunderstood that I have providedcomparatively simple, yet highly effective means for attaining thepurposes of the present invention.

Various changes may be made in the construction, and certain featuresthereof may be employed without others, without departing from myinvention as it is defined in the accompanying claims.
